Chinese rendezvous test?
It appears that the Chinese have successfully maneuvered two unmanned satellites to a rendezvous in space. It is even possible that they might have touched!

Paper extolling the benefits from interstellar spaceflight
This guy is thinking ahead: a paper extolling the scientific benefits of interstellar space travel (published in a 2009 issue of the Journal of the British Interplanetary Society) was made available today on the Los Alamos astro-ph website. Fun quote from the abstract:
Significant benefits are identified in the fields of interstellar medium studies, stellar astrophysics, planetary science and astrobiology. In the latter three areas the benefits would be considerably enhanced if the interstellar vehicle is able to decelerate from its interstellar cruise velocity to rest relative to the target system. Although this will greatly complicate the mission architecture, and extend the overall travel time, the scientific benefits are such that this option should be considered seriously in future studies.

Russia to begin construction of new spaceport
The Russian news agency ITAR-TASS reports that all the “i”s have been dotted on the plans to build a new spaceport in the far east of Russia. Construction is set to begin next year.

X-37B changes orbit
Amateurs tracking the X-37B military test shuttle have discovered that it has made two orbital maneuvers. Since the Air Force refuses to discuss the flight program, the reasons behind these maneuvers remains unknown.

Danes set to launch private suborbital rocket
Two Danish inventors are about to test fly their own privately financed suborbital rocket, designed to eventually carry humans. Key quote:
It is due to launch from a submarine in the Baltic Sea on August 30th and, if successful, they will repeat it with a human passenger on board as soon as possible.

X-37B spotted by amateurs
Not only have amateur skywatchers photographed the X-37B military space plane presently in orbit, they use a smart phone app for tracking satellites and available to all to tell them when to look.

Landing gear collapses on WhiteKnightTwo during test flight
Bad news for space tourism! One of WhiteKnightTwo’s landing gears collapsed as the plane landed at the end of a test flight yesterday. Here’s a statement from Scaled Composites, the builder of the suborbital rocket system.

Spacewalk update
The spacewalk on ISS is not quite finished, but the astronauts are wrapping up after successfully installing the replacement pump to the cooling system. Ground controllers have tested the system and it appears to be working.

The plans for the next spacewalks on ISS are announced
NASA managers have delayed by one day the next spacewalk to repair ISS’s cooling system. Now set for August 16, this spacewalk will install the new pump. The date of a fourth spacewalk to finish up the work is as yet unscheduled.

Japanese planning upgrades to HTV
The Japanese are considering upgrades to their unmanned HTV freighter that carries cargo to ISS. The upgrades would allow HTV to return large cargo to Earth, as well as possibly become a manned vehicle.

Fourth spacewalk anticipated for coolant repairs
With the success of yesterday’s spacewalk, NASA engineers have revamped their remaining spacewalk plans for replacing that failed pump. The third spacewalk has been moved from Sunday to Monday to give everyone more time to prepare, and they are now planning a fourth spacewalk after that to finish things up.

Spacewalk a complete success, old pump removed
Today’s spacewalk on ISS was a complete success. The astronauts successfully removed the failed coolant pump and made preparations to install the replacement pump on their next spacewalk.

NASA narrows asteroids to visit to three
NASA officials have reviewed the list of Near Earth Objects and found only three that meet all the constraints for a manned mission. Key quote:
Out of the 44 reachable asteroids, 27 were too small, and only 15 have orbits that allow for exploration between 2020 and 2050 — the timeframe NASA wants to pursue for NEO missions. The 180-day mission constraint further cuts the list to three.
It must also be noted that none of these asteroids are reachable without a heavy-lift rocket like the Ares V.

Rebuilding the American space program — the right way
In reading my post, Both for and against the Obama plan, reader Trent Waddington emailed me to say that this “is so fatalistic that it seems you don’t think it is worthwhile even spending a few minutes explaining why the policy is good. It’s easy to dismiss something a politician says as the stopped clock that is right twice a day. It’s harder to set aside your skepticism and explain why something is good policy.”
Trent is absolutely correct. What I wrote was very depressing and fatalistic. However, I think it very important to be coldly honest about things, no matter how bad they look. Once you’ve done that, you then have the right information necessary for fixing the situation.
My problem with most of the debate about the future space policy of the United States, — as well as innumerable other modern issues faced by our government — is that people don’t seem to want to face up to the reality of the problem. In the case of space and Obama, I doubt any advice, gentle or otherwise, is going to move him into putting forth a plan for NASA that has any realistic chance of getting passed by Congress. As I noted in a different post, he doesn’t play the game. He acts like the worst sort of autocrat, convinced that if he simply says what he wants to do, everyone must agree.
The reason the good part of his plan (commercial space) is not passing Congress is not because people think it is a bad idea. It is being rejected because » Read more
